First and foremost, you must look at the weighting of the marks for the question. You must check markschemes and examiner reports for the specific board to see if the marks for the question are more heavily ...

In a reaction between MnO 4 - and Fe 2+ we are told MnO 4 - goes to Mn 2+ and Fe 2+ goes to Fe 3+ . We then need to derive the redox equation for the reaction occuring. First we need to idenfity which specie...

We can differentiate this implicitly by writing the question as:y = 2 x Then we take the log of both sides:ln(y) = ln(2 x )Using the rules of logartithms this can be written as:ln(y) = x ln(2)Now we can diff...

to differentiate this equation we have to do it in two parts because there is a minus sign seperating them in the middle for the first part we first have to multiple the constant by what the power of x is wh...

Coincidence of actus reus and mens rea is the principle that both the mental and physical element of the crime must be present in order for someone to be liable for murder. This is often called the contempor...
